I'm trying to upgrade memory of an HP Probook 6550b laptop. I happen to have a Dell inspiron with 2 branches:
4GB PC3L 12800S Part number: HMT451S6BFR8A (manu: hynix)
The RAM on my probook should according to what I understand in this work (search DDR3 for references or go to p.4 of chapter one).
The computer will boot. System info at startup will show 8192 mb of ram, which is what I inserted (2 slots). However, when I try to actually boot it shuts down. Similarly if I try to run memory tests.
Note that I am trying to use a PC3L in a PC3 slot - but according to a similar question on this exchange, this should be fine.
Is there something I may have to do to make this work, or is the ram I'm trying to put in just not compatible?
